It is nearly impossible to compare the advantages and disadvantages of online shop systems because they are complex systems with a variety of functions, that build for different needs. I’m talking about such a system for small and micro-businesses, where processes can be built around the functionality of such systems to some degree. So this post can be only my personal impression of a system that I compared so far....
Everybody knows the drawbacks of Java Applets. Long loading times, browser freezing, and stability problems. That fact does not make java applet popular1. Most of those problems lie in the quality of the java browser plug-in itself, which was not really good and was not improved over a longer time. Sun has ground up rewritten the browser java Plug-in. Following was done in this rebuild. Improved scripting support (So javascript integration is better) Improved reliability Supports more powerful applets (applets can ask for more memory) Better windows vista support (signed applets) Enterprise features (run one applet in a particular JRE version) The last point sounds very interesting to me....
Don’t believe that? Than listen to the story… Occupational i deal with people who works with already aged version WSAD IDE (Rational Application Developer for Web Sphere). I think they use version 5 which is based on eclipse platform in version 2.0 or 2.1 where code folding was not supported. Code folding feature of eclipse based IDE allows you to clap currently not interesting code fragments like methods, constructors or import statements just in place in your current editor window....
In the genesis of Database Systems age, as triggers were proposed1, the goal of such DB mechanisms, was relatively clear. Triggers appeared for assuring and extending the control of integrity property in Database Systems: … Database Trigger is predefined database procedure, conditionally or unconditionally succeeding or preceding other database operations automatically…[IBM Research Report, RJ1820, 1976] The question That is actually what technically DB Triggers are still today. However having procedures (aka triggers) on the database level makes them available for anyone....
Yesterday W3C has published document named HTML5 differences from HTML4. Interesting here is that the standard provides two syntax variants HTML5 and XHTML5: HTML5 - is compatible with HTML4 and XHTML1 documents published on the web, but is not compatible with the more esoteric SGML features of HTML4. Documents using this syntax need to be served with the text/html MIME type. HTML5 also defines detailed parsing rules (including “error handling”) for this syntax which is largely compatible with popular implementations....
In last times i get more and more in contact with JavaScript. OK earlier i had just to adopt some of part of scripts for my needs, but with emerging of Ajax and Web 2.0 also i have more often do deal with JavaScript. So i need one appropriate Editor or better an IDE special for JavaScript. Someone told me, he is been using Aptana. I tried it and Aptana seem to be that IDE for JavaScript i was looking for....
The Java Persistence API (JPA) provides a POJO persistence model for object-relational mapping. The Java Persistence API was developed by the EJB 3.0 software expert group as part of JSR 220, but its use is not limited to EJB software components. It can also be used directly by web applications and Java SE application clients. So JPA is about persistence of the java objects or entities. An Entity is a lightweight domain specific java object that may be stored to persistent storage (mostly Relational DB)....
